Hypothesis
What are the associations between cardiorespiratory fitness, brain age, and neurodegeneration in older adults with amnestic mild cognitive impairment?
Conclusion
The study found that cardiorespiratory fitness was not associated with brain age and neurodegeneration, but brain age negatively correlated with hippocampal volume and cortical thickness.
Supporting Evidence
- Cardiorespiratory fitness was measured using VO2peak from a peak cycle-ergometer test.
- Brain age and neurodegeneration were assessed using structural magnetic resonance imaging.
- The sample had an average age of 73.63 years and an average education of 16.98 years.
Takeaway
This study looked at how being fit affects the brain in older people with memory problems, and it found that fitness didn't help with brain age or damage.
Methodology
The study used multiple linear regressions to analyze associations using baseline data from a trial.
Limitations
The study only examined baseline data and did not explore other potential brain indicators related to cardiorespiratory fitness.
Participant Demographics
Participants averaged 73.63 years of age, with 51.5% male and 92.5% White.
